This region is also known as the Jackson purchase because Andrew Jackson bought it from the Chickasaw Indians in 1818. It is adjacent to the Mississippi river and characterized by river bottoms and swamps. This is a unique area for Kentucky containing many coastal tree species more common to southeastern states. These include bald cypress, willow oak, pecan and sweetgum. Today much of this unique region has been drained and cleared for agriculture and habitation. A remnant wetland is preserved at Murphy's Pond in Hickman county.
